9.0mm Barrier Strip Terminal Block

9.0mm barrier strip terminal block which enables conversion from a screw-type format of wiring terminals to a higher pitch row of female connectors. To compensate for the larger spacings between the screw-type format of screw wiring terminals, the screw-type wiring terminals can be arranged in first and second rows, either staggered or not, one on each side of the row of female connectors. Individual female connectors in the row are connected alternatively with a screw wiring terminal from the first row and a screw wiring terminal from the second row.

Wiring Method of Barrier Terminal Blocks

1. Welding

The most common type of welding is soldering. The most important thing for the solder connection is that the continuity of the metal should be formed between the solder material and the surface to be soldered. Therefore, for terminal blocks, especially cold-pressed terminal blocks, solderability is important. The most common coatings on the soldering end of the ring terminal are tin alloy, silver, and gold. The reed contact has a solder tab type, a punching solder tab type, and a notched solder tab type for the common welding end. The pinhole contact has a drilled arc notch type for the common welding end.

2. Crimp

Crimping is a technique for compressing and displacing metal within prescribed limits and connecting wires to contact pairs. A good crimp connection can produce a mutual melting flow of metal so that the wire and contact deform the material symmetrically. This connection is similar to cold welding connection, it can get better mechanical strength and electrical continuity, it can withstand more severe environmental conditions. At present, it is generally believed that the correct crimp connection is better than soldering, especially in high-current occasions. When crimping, special crimping pliers or automatic or semi-automatic crimping machines must be used. According to the cold-pressed terminal and the cross-section of the cold-pressed end wire, the correct contact wire barrel should be selected correctly. It should be noted that the crimp connection is a permanent connection and can only be used once.

3. Winding

Winding is to wind the wire directly on the winding post of the angular contact. During the winding, the wire is wound under the control of the tension, pressed in and fixed at the corners of the winding post of the contact to form an airtight contact. There are several requirements for wire wrapping: the nominal value of the wire diameter should be in the range of 0.25mm~1.0mm; when the wire diameter is not greater than 0.5mm, the elongation of the conductor material is not less than 15%; when the wire diameter is greater than 0.5mm, the conductor The elongation of the material is not less than 20%. Tools for winding include winding gun and fixed winding machine.

4. Puncture connection

Puncture connection, also known as insulation displacement connection, is a novel terminal technology invented by the United States in the 1960s. It has the characteristics of high reliability, low cost, and ease of use. It has been widely used in various terminals for printed boards, cold-pressed terminal, cold-pressed end, and the ring terminal. It is suitable for the connection of ribbon cables. It is not necessary to strip the insulation layer of the cable during the connection. The tip of the U-shaped contact spring of the terminal is penetrated into the insulation layer to make the conductor of the cable slide into the groove of the contact spring and be clamped so that a tight electrical connection is formed between the cable conductor and the terminal spring. It requires only simple tools, but cables with specified wire gauges must be selected.

5. Screw connection

The screw connection is a connection method using screw terminal blocks, which allows the maximum and minimum cross-sections of the connecting wires and the maximum tightening torque allowed by screws of different specifications.
